EYELETlNG-MACHINE'.

SPECIFICATION forming part of Letters Patent No. 423,599, dated March18, 1890. Application filed March 19, 1889. Serial No. 303,862. (Nomodel.)

To all whom it may concern.-

Be it known that I, LOENDER O. EMERSON, of North Grafton, county ofWorcester, State of Massachusetts, have invented an Improvement inEyeleting-Wlachines, of which the following description, in connectionwith the ac-' companying drawings, is a specification, like and theeyelet-hole is made by apunch which descends on the material andco-operates with a movable die-block or anvil at the under side of thematerial.

In my improved machine the punch on its way into the material enters theeyelet held in usual manner at the end of av raceway or other equivalentsupport, the punch passing through the eyelet.

The punch described is made longer than, and is arranged inside of, ahollow set, both the punch and the set having co-operating means,whereby they may be actuated independently each of the other. In thismanner after the punch has entered the eyelet and punched the material,the set, while the punch is yet in the eyelet, is moved to act upon thelarge end of the eyelet and drive it from the punch, while the, latteracts as a guide, into the hole previously made in the material by thesaid punch, the punch having in the meantime been partially raised, butpreferably not far enough to lift it above the face of the material. Thepunch having been moved to punch a hole in the material, as described,the die-block or anvil referred to is quickly turned aside, and the setco-operating with the one surrounding the punch is quickly raised intothe position occupied by the anvil when the punch entered the material,and

as herein provided for both sets are made to approach each other, and inso doing act to upset both ends of the eyelet. The punch is lifted fromthe eyelet just before the two sets act to upset the eyelet. 1

partially broken out.

let so that the punch might enter it on its way to punch the material.

. means to support or hold and presentthe eye- In my improved machine Ihave so constructed the eyelet-feeding mechanism that the eyelets arefed into the raceway consti-' tuting a support for them with their largeends uppermost, and to enable this to be done unerringly I have extendedinto the eyelet hopper one or more receiving branches, into which theeyelets can enter in only the right way, a brush or other usual sweepmoving the eyelets along the said receiver or receivers into theraceway. The raceway has imparted to it a longitudinal movement awayfrom thevpunch just after the punch in its descent through the eyelethas entered the material.

In other earlier machines the undermost set, madetubular, has containeda spring-pin, which,after the material has been acted upon by a punch tomake a hole therein for the eye-:

let, has entered the eyelet at the end-of a raceway just before theraceway was moved longitudinally, and the said pin has been pushed backinto the lowermost set against the spring supporting it by the end ofthe uppermost set.

Figure 1 in front elevation shows an eyelet-' ing-machine representingone form of my invention to be herein described, the downturned frontend of the work-support being broken out. Fig. 2 is a sectional detailof the hopper and the upper end of the raceway and receiver; Fig. 3, asection-of Fig. 2 in the line 00. Fig. 4 is a detail showing threeconvergingreceivers leading to one raceway. Fig. 5 is a partialleft-hand elevation of the machine shown in Fig. 1, the frame-work beingFig. 6 is a section of Fig. 5 in the dotted line as"; and Fig. 7 is a.detail looking upwardly from the dotted line 00 Fig. 1, chiefly to showan under side view of the-devices immediately below the said support,the ,arm g? and the link 12 being broken oif.

The frame-work A is and may be of suit-' able shape to'sustain theworking parts.

The main shaft A, provided at one end with any usual form ofdriving-pulley, preferably some form of clutch-pulley under the controlof a treadle, (not shown,) has on it two eccen tries a b, a cam c, and acrank-pind.

.The eccentric-strap b surrounding the cocentricb is represented asbroadened and cut out at-its upper end (see 'Fig. 5) to receive a spiralor other spring b through which is extended a threaded rod 6 upon which,below the lowerend of the said spring, is applied a suitable nut, theupper end of the said rod being provided with an eye to embrace asuitable pin or stud b of an arm 12 fast on a rockshaft'b, the said rodentering loosely the upper end of the said eccentric-link. The rockshaftb has a second arm If, to which is connected a link I), it, at its lowerend, engaging a stud b on the upright rod b of the carrier b Z2 to theforward end of which is secured by screw 19 the hollow or tubular upperset I). The spring b enables the set I? to yield 'to the thickness ofthe material.

The eccentrica is shown as surrounded by an eccentric-strap rod a, whichat its upper end is connected to a stud a of an arm a fast on arock-shaft a (shown only in Fig. 6,) the said shaft being parallel tothe shaft b and having a second arm a to which is jointed a link a", thelower end of the link being connected to a stud a projected fromthe roda having at its upper end an arm a to which is secured by a suitableset-screw, or in other usual manner, the punch 19, the'said punch beingextended down through the hollow upper set b the two eccentrics being soplaced on the shaft A as to move the said punch and upper setindependently, the punch always remaining in the upper set, and, asherein represented, the lower reduced upper end of the punch is guidedby the set. The rod a is reciprocated 'in the guide-stand as a. Thecrank-pin d is extended from a disk A con.- nected to or forming part ofthe main shaft A. The crank-pin (1 receives a link d, which at its lowerend embraces a stud 01 shown as extended from a collar (i secured to thelowermost set d by a set-screw d, the said set d reciprocating in apost-like guide d secured rigidly to the frame-work. The upper end ofthe set d is reduced, as seen in Fig. 5, to leavea small point to enterand remain in the eyelet after the latter has been discharged from thepunch by the set I), the said point acting as usual to prevent theeyelet from being crushed while being set.

The hopper B, preferably a circular shell,

having a feeder B is mounted on a carriage B having, as represented, adovetailed foot 13*, which is free to slide in a similar-shaped guidewayof a block 13", secured to or forming part of a stand B The hoppercontains a wheel B (shown as a brush,) it being fast to a shaft B,extended through the-hopper and provided with a pinion B which isengaged by a toothed sector B pivoted on a stud B the said sector havingconnected to it a rod B which at its lower end is jointed to a stud orarm 13, fast to the rock-shaft a, (see Fig. 6,) the said rock-shaft,through the devices described, oscillating the said wheel in the hopper,so as to sweep'the eyelets 2 from the receivers f into the upper end ofthe groove of the raceway f the said raceway having at one side itscentral open groove a cover, as f to keep the eyelets large'end up inthe said groove. This raceway is secured to or forms part of an arm ofthe carriage H, as best shown in Fig. 1. The raceway constituting asupport for the eyelet to be entered by the punch and next to be set hasat its lower end any usual form of detent, as 3, preferably some sort ofa spring to keep the endmost ,eyelet of the row of eyelets in theraceway in place to be entered by the punch 19 as it descends to punch ahole in the material lying on the table 9, the said detentyielding,how-' i ever, readily to permit the removal of an eye'- letfrom the raceway or support after the same has been entered by thepunch, the said raceway being at such time moved longi'tudinally' awayfrom the punch by a rock-shaft e one arm e of which is connected looselyto a stud or projection'e'of the carriage E the said shaft having asecond arm, as a one iend of which is normally held by a spring 5 in therange of movement of a stud 6 ex- ;tended from the arm b The spring5 iscongnectedat one end to a stud of the carriage B -;and at its other endto a stud 6 of the guide I13 The rock-shaft e has its bearing in a block6 at the upper end of i a stand e the said block, as shown, havingsleeve-like exten- Isions at each side. The work-support g, supportedrigidly on firocates the serrated feed-bar g and a small opening 7, inwhich stands and moves the.

anvil hwhen not in operative position. The isupport g has depending fromit a guide 9 in which reciprocates the feed-carrying slide 5g, it havingextended from it the arm 8, to which is secured the feed-bar 9 The arm 8,has connected to it loosely a link 12, jointed at its other end by astud 13 to one arm of a rocker-lever g having astud g which takes 'abearing in asleeve 20, herein shown as fixed to the support 9. Theopposite arm of the said rocker-lever has jointed to it a link g, inturn jointed at its other end to a lever 14, pivoted at 15 to theframe-work.

The lever 14 is shown as grooved at itsinher side (see dotted lines) toreceive a pin 16, extended from a regulating-block 17, ad-

Ice

0, having a second arm 0 provided with a roller-or other usual stud 0which enters the groove of the cam c. The elbow-lever g in its movementsreciprocates the slide g and actuates the feed-bar to move over thesupport g intermittingly the material in which the eyeletis to be set,adjustment of the block'17 providing different lengths of feed.

The slide g 'has at one side an extension, in

which is placed a presser-bar 23, having in it a vertical passage forthe reception of the said presser-bar, the latterhaving an arm 24, thefront of which is provided with a suitable resser-foot 25, to keep thematerial down on the feed-bar and the support 9, the said presserbeingacted upon bya suitable spring, as 26, (see Fig. 5,) which normallykeeps the presser-foot pressed down.

The presser-foot, it will be understood, will move forward-in unisonwith the feed-bar;

but when the feed-bar is being moved backwardly the presser-foot iselevated from the material by, asherein shown, a lever m, pivoted at 29onthebar 9 the said lever being connected by a rod 30 to a stud 31 of alever m having its fulcrum at m and provided wit-h a roll 34, which inthe rotation of the shaft A is struck by a cam 35, forming'part of thedisk (I. The lower end of the rod 23 has a roller 28, which obviatesfriction between the bar and the lever m.

The support 9 has pivoted to it at 40 one end of the lever 42, which ator near its other end has attached to it the punch-block or anvil h, thesaid lever being slotted to receive a roller or otherstud 43 of an arm44, ex-

tended from the slide 9, themovements of the said slide, when operatingto effect the forward or feeding motion of the material,

acting through the stud 43 to vibrate the lever 42 and place thedie-block or anvil in position immediately in the path of movement ofthe punch 19, the lower set 01 being then down, as in Fig. 5.

During the feeding movement of the material the punch p commencestodescend, and in its descent enters the large upper end of the eyeletat the lower end of the racewayor support, the said punch continuing itsdescentand meeting the material just as the feeding-stroke is completed,the punch strik-,

ing the material immediately above the punch-block or anvil and makingtheusual hole for the eyelet. The hole having been made, the punch israised slightly (in practice about one-sixteenth of an inch) to relievethe punch from the punch-block, and then the feed starts back quickly,the slide g in its backward movement (the foot being then by the upperset 11 it having been actuated and moved downwardly, but not until justafter the raceway was pulled or moved backwardly far enough to retirefrom the eyelet then on the punch, the downward movement of the set I)after the removal of the eyelet from the raceway pushing the eyelet intothe material.

The movements of the two sets I) and d are preferably such that aftereach comes in contact with opposite ends of the eyelet both of the saidsets have sufficient movement one toward th'eother to upset the eyeletin usual manner, the 'punchretiring. from the eyelet just before thelatter is fully upset. v. 4 n

It will be noticed that the receivers extend into and partially surroundthe brushB The grooves in the receivers (see Fig. 3).are narrower attheir lower than at their upper parts, so that the eyelets can entertherein only with their small ends down, the brush in its movement inthe direction of the arrow, Fig. 2, acting to sweep the eyelets lodgedin the said receivers into the raceway, down which they slide. The brushin its backward movement brushes from the tops of the receivers anyloose eyelets therein and not properly entering the grooves of thereceivers.

I I do not desire to limit my invention to the exactform of hopper orbrush, nor to the exact form of feeding mechanism; but instead may useany other well-known equivalent devices.

I claim W 1. In an eyeleting-machine, the combination, with a supportfor the eyelet ,to be set,
